CHIROPRACTIC TABLE.

Specification of Letters Patent.

JOSIAH M. MIYERS, OF DAVENPORT, TOWA.

Patented ct. 22,'1'92.

y Application led Junell, 1912. .,Seral No. 701,004.

To all whom it'may concern:

lie it known that I, JOSIAH M. MYERS, citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Chiropractic Tables, of which the following is a specilication.

My present invention pertains to surgical tables, and contemplates the provision of a table constructed with a view to being usedl to advantage by chiropractors in manipulating and treating patients incidental to the practice of the chiropractic science.4

The invention in all of its details will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of the specification, in which:

Figure l is a perspective of the table constituting the best practical embodiment of my invention that I have as yet devised.

F ig. 2 is a'longitudinal section of the same. y

Fig. 3 isa horizontal section taken'in the plane indicated by the line 3-3 of Fig. 2, looking downward. Fig. 4 is a detail longitudinal vertical section illustrative of the manner in which the rear bench can be adjusted. Fig.- 5 is a horizontal section taken in the plane of the line 5 5 of Fig. 2, looking upward, and showing the mechanism for adjustably fixing the rear bench in position. Fig. 6 is a transverse section taken in the plane indicated. by the line 6 6 'of Fig. 2, looking toward the right. Fig. 7' s a transverse section taken on the line 7-7 0f Fig. 2, looking toward they left. Fig. 8 is a transverse section showing the lock'comprised in the table.

Similar numerals of reference designate corresponding parts in all of the views of the drawings. I

Among other elements my novel table comprises a main frame, preferably of metal or wood and mountedupon legs, also of metal. The main frame is oblong and comprises sidebars l, of T-form in cross-section,

and end bars 2. The legs 3 are fixed to the main frame at the corners thereof.

Fixed to and rising from the side bars v1 are standards-4, and pivoted to and deslgned to be swung vertically on the said standards et is what I denominate the head bench 5 of' -l the table; the said bench'being composed of a .base or 'frame and a cushion appropriate By grasping the vsaid lhandle y8 the chiropractor is enabled to conveniently manipulate the rack-bars and place the same engagement with one Vend bar*4 of the main frame. It will also be observed that `through the medium of theV rack-bars 6-the head bench 5 can be placed ina variety of linclined positions according to the needs `of the patient on the table, and that the curvavtureof the said rackbars 6 is sucli'tas to ,Ipermit of a Vwide range of adjustment without liability of the said bars contacting with the floor, `notwithstanding the slight distance 'of the frame above' thefloor whichz'is advantageous because it does not interfere `with the knees oftlije.' chiropractor-- nor l with the abdomen vof .a stout person and yet affords ample room below the frame for the feet Aof th chiropractor;l (lIisposed 0n and movablelongitudinally of the main frame is' a carriage onwhieh as hereinafter described the-'rearlbench 4of the table is carried.- The said carriage' is made up of steel side bars 9', of 'right angle form 1n cross-section, and cross rods 1 '0 extending between and xedly connecting the side bars, the outwardly extending horizontal portipns ol' which are arranged upon the upper sides of .the frame bars 1 between which frame barsthe longitudinally movablecarriage isguided in its movements. i

Suitably fixed to and rlslng from the 1n'- ner portions ofthe carriagebars 9 are standards ll1, and pivoted to the said estandards so as to swing vertically thereon is ,the rear bench of the table. The said bench may be of any construction compatible with the purpose of my'invent'ion without involving departure from the scope. of the same4 as claimed. I prefer however to havetherear bench comprise a lower frame 12,pivoted at 13 yto the standards 1'1, *an upper frame or board 14 rpivoted to the outer. endof the i v thereon.

frame 12, and suitable cushioning means 15 'arranged on and connected to the framey or boardlt. The frame 12 is pro-vided with a cross rod 16, and pivoted to the traine or boarduli are connected racll' bars- 17 designed' and adapted to be engaged with the rod' 16 for the purpose of adjustably fixing -thecushion of the benchat various angles "of inclination with respect to the frame-12.

of the 'carriage so as toadjust-ably supportthe frame ,12 in various posi-tions. One of the raclebars 18 is providedl with a handle 19 similar to the handle 8j complementary lto the rack-barst.v I would here directattention v`to the fact that through the medium of the means described both of 'the benches can be placed .and supported in downwardly inclined positions" from their centers of Inove-A lment as 'well as inupwardly inclined positions from saidfeenters' also, that 'each of' thebenches is ta'pable of being adjusted and adjustablytixed independently of the other so`tha-t as voccasion demands both benches may beinclined upward from their centers lof movement-or one bench can .be inclined vupward from its center and the other can `be inclined downward from its center or one bench can be maintained horizontally vwhile the ,otheris inclined either upward or downward, orboth benehescan be inclined downwardly from their centers of .'movement'. .By virtue of this adjustability of the Ibenches and the facility with which the rear bench can be moved outward v'and inward, it vwill be manifest that the chiropractor is enabled to .conveniently place a patient vin la wide variety oi positions, and this without subjecting the patient to discomfort. I Awould also have it understood here-that the overhang of the head' bench enables the chiropractor to adjust the cervical vertebra of a 'patient Without liability of the chiropractor lrickingthe feet of the main frame and thereby moving thetableand the patient stooping, while the downward inclination of the rear bench'lexes thehip joints of a patient so as to bring about opening-of the.

standards 4 is one end of a flexible support The height vto which the headv bench 'may befraised enables the chircprac-v tor to adjust the cervical vertebra without,

claim anddesire to secure by Letters-Patent, is:

incassa for the abdomen of a patient. The said support may be made or' webbing or other material suitable to its purpose and it is carried 4from its said point oit' connection to a point between the standards ll'on the carriage, where it is passed over asupporting roller20 and under a roller 21, both of which rollersfare carried by and extend between the standards 11; The outer end of the abdominal support, which is numbered 22, connected to one end of retractile springs 23 the other ends ofl which are connected with the adjacent end bar of the main frame. The abdomen support- 22 gives asense ot' security to the patient by par tially sustaining the weight of the abdomen,

and by reason or the arrangement described `the said support 22 is enabled to accommodate itself to the length of the space be tween the inner ends of the benches, when the rear bench-4f. e., the bench on the cari'iage, is moved outward or inward.

Carried by the slidable carriage is a frio. tion lock which has for its oihce to engage the main frame and set the carriage rigid at any point on the main frame within the -liinit of adjustment of the carriage. The

said loclr is numbered 25 and is `provided with a handle 26.

The arrangement described vof the abdosupport tothe spring 223 assures the said support being held under uniform tension I irrespective of the position of the carriage and rear bench.

When desired the-head bench ofthe table may be constructed in the same manner as the rear bench without involving departure from the scope of my invention. l The lock-,25 referred to` compris/es in addition to the handle 26 a rock-shaft 27 to which the handle- 26 is fixed, whichl rockshaft is j ournaled in the depending portions of the bars 9, "and arms 28,preferably stove bolts secured by lock nuts 29 tothe ro'clc shaft, designed to be moved against the uridersides of the frame bars 1. When the han dle 26 is upright the carriage is locked'to the frame, while when said handle isswung downward the carriage may beI moved on the frame. j

Rods `30 of cold rolled steel are secured on the frame bars 1 and disposed between the same and the carriage bars.

Having describ d my invention, what l `1. ln a chiropractic table, the 4combination or a main frame; a support Xed to and rising therefrom, /a vertically adjustable bench pivoted to and "extending loutward vtrein said support, curved rack bars connected together, and pivotcd to the -bench in position to'engage a portlon of the'mam frame, a carriage slidable on the'main vtranne `men support and the connection of the said ico iso
